Bad written player arguments on a command block in a server makes the client crash for every online user, and they can't enter again due to a "received string longer than allowed" error when trying to log in.

You can see the error with more detail in the "server.log" attached.

Please write what the exact argument was here.

I can't write it properly here, but it's visible in the 8th line of the server.log attached. Also, it can only be fixed using world backups.

If the command block can't understand what you're trying to say, you should expect weird behavior. For future reference, adding a \ before [ and ] will fix your problems.
